Can not access DfsrPrivate

  • 772

I've set up DFS-R between three servers, and so far, it is replicating everything as its supposed to.

  • The problem is, I can not access the DfsrPrivate folder. Where is it located? So far I see the link/shortcut from within my replicated folder. But I get an access denied, when trying to open it.

    I can open and browse the DfsrPrivate when I'm trying to specify another staging folder through DFS' own configuration, but I can not see files, only folders.

  • Do files/folders I deleted while having an active DFS replication group, get deleted permanently or does it store it in the Deleted folder under DfsrPrivate?

  • Another "bonus" question: If you're dealing with around 500gb of images, how large a staging quota do you recommend? Is there any "Best Practice"?

Thanks.

    You need to be a Domain Admin to override the permissions and view the DfsrPrivate folder (located in the DFS root folder; should be able to pull up \\domain\dfs_root\DfsrPrivate). It does contain a Deleted folder within it, but it should manage the size of that folder automatically. Deleted items are moved to the Deleted folder until all partners in the replication have moved it there, then it's actually deleted.

    The Staging size must be at least as large as the largest file you want replicated (best practice: take 10 file from the 10th percentiles, the staging should be the sum of their sizes).

  2. 1. Access problem: run elevated.

    On Win2008r2: Kill explorer. Restart explorer from elevated shell.

    From an elevated CMD:

    tskill explorer & explorer

    See also: How do I run an elevated explorer on W8R2 with default UAC?

    2. "Deleted" folder only used when checkbox non-default.

    Short explanation here. Long explanation see link.

    • In the default configuration that folder is not used and will remain empty. Instead killed files are placed in ConflictAndDeleted until that quota runs over. Then they are thrown out. Then that's permanent.

    • In the non-default configurations, the Deleted folder will be used as a very, very brief temporary cache for death bound files when the execution order has just come in from an outside DFSR partner server. That's permanent then. (Please excuse the violent language.)

    In depth explanation by Ned Pyle see below.

    3. Use at least sum of 32 largest files for staging size.
